Specification of Letters Patent. Patented June 15,1920.

I Application filed December 16, 1919. Serial No. 345,167.

To all whom it may concern: I

Be it known that I, JOHN S. BRENNAN, a citizen ofthe' United States, and resident of Milwaukee, in the county'of Milwaukee and State of Wisconsin, have invented certain newand useful Improvements in Fuelbottom of the auxiliary receptaclefwhereby,

a constant level of fluid is maintained in the auxiliary receptacle, said level beingv determined by the bottom of the mouth or discharge neck of the main receptacle which projects thereinto, said valve member closing upon lifting themain receptacle from the auxiliary receptacle to prevent spill-' ing of the oil in manipulating the main receptacle for the purpose of replenishment. 7 It is the object of my invention to increase the strength and the firmness of support afforded to the main detachable receptacle by the auxiliary receptacle having the usual rigid connection with the stove struc-' ture, and to increase the efficiency of devices of this character particularly withrespect to insuring the provision and maintenance of a proper fluid level in the auxiliary receptacle for cooperation with the burner members of the stove.

My present structure is intended for use in connection with burner members whose burning action is controlled by raising'or lowering them with respect to the constant level fluid line and in View of the mechanical connections in procuring movement of the burners it is highly important that the constant fuel level lie in a predetermined plane with respect to'said mechanism.

In view of the fact that the glass bottles employed to form the main supply recep tacles of stoves are provided withnecks of varying length, and have heretofore been supported by seating of their shoulder portions in definite relation to the auxiliary receptacle, the constant level line has heretofore varied in accordance with variation of the length of the bottle necks. It is therefore particularly my object to provide a support means for the main receptacle wherein the vertical support is afforded by means having definite relation to the end of the bottlenecks so that a constant level; of fluid would be maintained in the auxillary receptacle irrespective ofvariation of lengths of the bottle necks.

With the above and other'objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of the parts as hereinafter described and'defined by the appended claims. v

In the accompanying drawing:

The figure shows a vertical sectional view through my improved reservoir and control valve structure.

Referring now more particularly tothe drawing 5 designatesthe usual pan shaped auxiliary receptacle of an oil stove having,

thesupply pipe 6 depending from its bottom at one side and in the present instance a plurality of upstanding arms 7 are secured to the "Wall of the" auxiliary receptacle 5 and are connected'at their upper ends by a band'8 which slidably receives and forms alateral support forthe main receptacle 9, which comprises as usual a glass bottle having a valve cap 10v threaded on its neck. It will, however, be appreciated that the wall of theauxiliary receptacle 5' may be extended upwardly to form a lateral support for the body of the main receptacle '9 and the band 8 may conse= quently be termed'an'extended portion of the auxiliary receptacle, the essential feature of support, novel in the present inbottle is not afforded a seat.

As shown in myco-pending application for patent filed Oct. "6, 1919, Serial'No.

828,796, the valve structure carried by the cap 10 comprises an inner valve casing sectionll secured within the cap about an outlet port formed by a central aperture in the bottom portion of the cap, the cap material adjacent said aperture being inclined to form a frusto-conical seat for cooperav tance, being that the end shoulderof the tion with the flared upper end of a tubular valve member 12 passed through the cap aperture, said tubular member being closed at its outer end and resiliently urged outwardly by a spring 13 disposed therein and bearing against said closed outer end and V the main receptacle into the auxiliary re-' against the casing portion 11. The outer portion of the tubular valve stem 12 is slidably passed through a bearing plate 1a which is spaced from and connected with the end of the cap by the arms 15. Thus when the main receptacle is inverted over and lowered to engage its neck portion into the auxiliary receptacle 5, the stem of the valve member 12 will engage the bottom of the auxiliary receptacle and will hencebecome disengaged from its seat on the cap 'member, thus permitting oil to flow freely from ceptacle, to a constant level 'line Which is determined by the end of the cap 10 threaded on the bottle neck To insure that possible variation of the length of the bottle neck will not effect the desired plane of the constant level, I associate the vertical support means for themain receptacle with the cap 10 and thus in the present instance I'provide a v plurality of divergent legs 16 on the cap member which seat on the bottom of the auxiliary receptacle. It is, however, noted that the upper end of the valve member-is afforded a seat in its open position by a shoulder portion 17 of the casing member 11, and thus the valve member, also forms a vertical support for the receptacle, and I may utilize thisseating of the valve member, in its open 7 position as the sole support.

I have thus provided an exceedingly simple structure for mounting a main fuel supply receptacle in such manner that variation in size of portions of the receptacle will not interfere with the procurement of a desired f constant level fuelline when the receptacle,

which would be formed of glass, is associated with the more accurately proportioned metallic parts of the stovestructure,

andrit will be noted that a firm and more positive vertical support is afforded in the present instancein contra-distinction to supports engaging intermediate or shoulder portions .of the main receptacle.

While I have'shown and described a preferred embodiment of my invention, it will be appreciated that various changes and 'modifications of structure may be employed to meet differing conditions, of use and manufacture, without departing in any manner from the spirit of my invention.

What is claimed is: 1. In a constant level fuel supply structure, an auxiliary receptacle, a main recep a valve cap secured on the neck of the main receptacle and vertical support'means for the main receptacle carried by said cap.

, 3. In a constant level fuel supply structure, an auxiliary receptacle, a main'receptacle having its neck portion engaged inthe auxiliary receptacle, means for supporting the, main receptacle against lateral move ment, a valve cap secured on the 'neck of the main receptacle, a valve structure car ried by the cap and including a movable valve member having a stem engage'able with the bottom of the auxiliary receptacle to open the valve, said'valve member being adapted to seat in the valve structure in open position whereby said stem affords a vertical support for the main receptacle, andfsaid lateral support means for the main receptacle permitting vertical movement of the inain receptacle toprojcure said seating engagement of the valve member. at. In a constant level fuel supply structure, an auxiliary receptacle, a main recep tacle having its neck portion engaged in the auxiliary rece tacle, a, valve cap secured on- .the neck oft e main receptacle, an aperturedbearing membercarried 'bythe cap in spaced relation thereto, valve mechanism carried by the cap for controlling flow of fluid therethrough and including a stem slidable in said bearing member, said stem being adapted to afford vertical support for the mainreceptacle and means for support ing the main receptacle against lateral movement, said means permittm-g vertical movement of the'main receptacle to effect its 7 vertical support bythe stem.

In testimony that I claimthe foregoing I have hereunto set my hand at Milwaukee,

in the c'ounty of 'Milvvaukee' and State of Wisconsin.
